Directors, or any other action which may be taken at a meeting of Directors, may
be taken without a meeting if a consent in writing, setting forth the action so
taken, is signed by all of the Directors entitled to vote with respect to the
subject matter of the meeting. The consent will have the effect of a unanimous
vote and will be equally valid as if the action were approved at a meeting.

for their services, but by resolution of the Board of Directors, a fixed sum and
expenses of attendance, if any, may be allowed for attendance at each regular or
special meeting of the Board of Directors. Nothing in this section will be

capacity and receiving compensation therefor.

purpose, any Director or the entire Board of Directors may be removed, with or
without cause, by a vote of a majority of the shares then entitled to vote at an
